Here’s something I’d never had to do before. Be careful as this kind of tip will only popup for you once on the first emerge.
# emerge dev-php5/ZendOptimizer
>>> cfg-update-1.8.2-r1: Creating checksum index...
Calculating dependencies... done!
>>> Verifying ebuild Manifests...
>>> Emerging (1 of 1) dev-php5/ZendOptimizer-3.3.0a to /
!!! dev-php5/ZendOptimizer-3.3.0a has fetch restriction turned on.
!!! This probably means that this ebuild's files must be downloaded
!!! manually. See the comments in the ebuild for more information.
* Please download ZendOptimizer-3.3.0a-linux-glibc23-x86_64 from:
* and put it into /usr/portage/distfiles/.
* Please note that you need a valid Zend Account
* (free) to download the Zend Optimizer!
Manually pushing the archive into distfiles and running
emerge worked fine. For a moment I was concerned that I might actually have to build something from source. Whew!
